Code P0109 2020 Ford F150 Description

The Manifold Absolute Pressure (MAP) Sensor is located on the intake manifold and measures the intake manifold pressure. The Powertrain Control Module (PCM) uses this information to determine the air charge and to provide the input for various engine control functions. Under normal operation, the greatest pressure that can exist in the intake manifold is at ignition ON, and engine OFF, which is equal to the Barometric Pressure (BARO). The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range. The sensor translates this action into electrical resistance. The MAP sensor may be integrated with an Intake Air Temperature (IAT) sensor. The Diagnostic Trouble Code (DTC) will be set when the MAP Sensor signal is intermittent.
